Support Docker distribution builds for ppc64le, arm64 and s390x

[reta]

Description

Support Docker distribution builds for ppc64le, arm64 and s390x. I got access to a few boxes found out the Docker containers we build only target aarch64/x86, however tini support ppc64le, arm64 and s390x as well (see please https://github.com/krallin/tini/releases).

CHANGELOG.md (1)

32-32: Changelog entry looks good.

distribution/docker/src/docker/Dockerfile (1)

31-37: No action needed; tini v0.19.0 includes ppc64le and s390x assets.

The v0.19.0 release of tini provides all required binaries and checksums for the new architectures added in lines 34–36, including tini-ppc64le, tini-s390x, and their .sha256sum files. The build will not fail on these architectures.

Likely an incorrect or invalid review comment.
